This morning I watched a video of Paul Franklin talking about his compensators as the way he keeps his guitar in perfect tuning both in the open position, as well as the pedals down position.

Sure enough, when I sat down at my guitar and voiced a minor triad using strings 7,6,5 with A & B pedals down, that 7th string was out of tune.

I’m now at the point, after playing for 3 years, where my body is comfy making moves to play steel, and my brain is ready to start fine tuning the sounds I hear in my head.

So, my question is this….does my Mullen RP already have compensators? Where would they be? Are they extra nylon tuning nuts? Or are they found somewhere else? These are different than splits, right?

Compensators such as what would be used on the strings 1 & 7 are simply changes that flatten the strings. They will look like any other pull. Bellcrank, rod, nylon tuner.

What Jon says. Don't be confused if you hear about other "compensators" which are gadgets for correcting mechanical limitations in the structure of some guitars.

The ones we're talking about here have a purely musical purpose. I have two pulls, one from each of the A and C pedals to the 7th string. They lower it slightly. I don't need anything on string 1.

My main focus is to see if there is a way to keep my 7th string (F#) in tune for voicing minor chords with A&B pedals pressed on 7,6,5….

When I use the 7th string as a major 7th with the open chord, it sounds in tune. When I use it for a minor chord with A &B pedals pressed, it is out of tune.

How would I be able to tell if there is a compensator on that string?

Ok, I’ve learned that there are not compensators on my guitar. Any suggestions to get the 7th string in turn for the above mentioned application?

You can contact Mullen and order the parts to add a compensator.

All you need is one crank to fit to the A pedal shaft, one pull rod and a nylon tuner if you don't have a spare one already. If you want to connect the C pedal as well (which makes sense) then double the dose. This assumes you have two spare lower holes on the changer.

On some guitars, you can do the A pedal and the C pedal comp with a single rod, two pullers, and one nylon tuner; but only if your guitar uses round puller pins with a screw, like the MSA. (It won't work if your guitar uses bent rods and a clip.) Cool

My Emmons' changer is 3+2. I've often wished that I'd had a couple of compensators fitted when I first ordered it but it would have meant 'losing' options at the changer.

Good that you're able to hear the problem. Just my humble 2 cents here, but I'd think a more empowering route than simply putting compensators on you guitar would be to try to understand why the F#(s) create this issue and what the source of the problem is from a tuning perspective. (There are plenty of threads on this exact topic). This will force you to be more conscious of what part of each chord you're occupying when you use those strings. Similarly, using preset 'sweetened' tunings works for a lot of players, but understanding why and how the offsets work as they do will ultimately inform your playing in a more thorough way.

Andrew, I’m in complete agreement. I gave Mullen a call, and they mentioned that 99% of their players do not use compensators because they don’t need to. This leads me to believe that I’m doing something wrong, probably due to inexperience.

I use a Peterson tuner, and stick to the sweetened SE9 and SP9 tunings. I may experiment with the OE9/OP9, or the EM9/EP9 tunings to see if there is any difference.

I’ve also been able to adjust my bar technique to get the 7th string in tune with a slight slant. Ideally, I’ll be able to find a tuning that allows me to keep the bar straight, but if not, I can make it work….

Not sure if anybody is interested, but I just tuned, retuned, and retuned my guitar using the various presets on my Peterson tuner. Far and away, the best and most accurate tuning was the OE9/OP9 tuning. Open chords, pedals down, as well as using the 7th string were all in tune. Even my LKL was closer to being in tune on diminished chords (but still perfect on major chords using LKL/B pedal)

I'll second what Andrew Frost said.

I use a bunch of compensators to sweeten many chords. I tune the open F# string 7 to be in tune with an E lever B major. I lower string 7 a smidgen with pedal B, for a sweetened A+B Amaj6 chord. That also sweetens the open DMaj7, strings 9-7-6-5, with A+B engaged. The lower 3 strings are a sweet D major, the compensator flattens the major 3rd note to be in tune with root and 5th.

Hope this helps. BY THE WAY, I tune just one string, open 4th string E (pedals down) and tune the rest of the guitar with harmonics to get the steel really in tune with itself.

John, it seems that like me you tune in natural intervals, where there's no choice but to lower the 7th string slightly as required.

Several notes on my universal come in two sizes. For instance the 5th string C# on P7 is sharper than on the A pedal, and so on.

There are a few conflicts that don't resolve*, but I work round them for the sake of the sonority I get generally.

* mostly around dim and aug chords. Four stacked minor thirds come to more than an octave, and three stacked majors are less; so some of these chords sound more convincing than others.

I accept that the majority of guitars out there may not have any compensators; my Emmons certainly doesn't. It's also true that one can play one's way around the 'trouble spots' with judicious bar-manipulation and get pretty close. That comes with experience.

It's a compromise, though. I wish I could go to any inversion of any chord on either neck and not have to worry about how out-of-tune it's going to be. That would require a fair few compensators.

I agree. I most certainly don’t consider myself an expert steeler, but I do play pedal steel often in my studio, and on a few recordings of my own (as well as a few artists’ who were unlucky enough to hire me).

In a live situation, I can adapt and make the slightly out of tune sound work. In the studio, I would like things to be perfect..

My view exactly, so I make sure they are...

So, I think I’m gonna go for it and have tuning compensators added to get strings 1&7 in better tune. I’m hoping for a bit of clarification…..

Where should the compensators go? I’m thinking they should go on B&C pedals to slightly lower 1&7. Sound right? Or should I be adding more? Less?

I don’t want to overcomplicate my guitar!

It might be good to point out here that those who use the Newman/Peterson tuning or use Meantone don't need compensators at all. The "Two F#s" problem is solved in a different way, and that's by tuning all of the 5th intervals of the most common chord positions 4 cents flat of "pure" (in Newman) and 5 cents flat (in Meantone).

The trade-off for fixing that "Two F#s" problem is making every chord slightly less 'in tune' sounding than it might otherwise be. But it works well enough overall and I used Newman for a long time before moving to a system that's more internally consistent (we'll leave that for another thread), and one that's customized to the cab drop and raise on each guitar. But that system needs a compensator to end up with 'the best of all worlds.' It's a brilliant solution.

My opinion:

Compensating string 7 is way more useful than string 1, for two reasons. It's used more often as part of a chord -- and tuning outages are more noticeable when intervals are sustained -- and because you can't bar-slant your way out of trouble on a triad where the offending note appears on the middle string in the grip, as it often is on string 7. But it's simple to correct string 1 with a micro-slant, since it's out on the edge of the grip.

So, I compensate string 7, and bar slant string 1. It's a very small slant on string 1. No big deal once you incorporate it into your playing.

I love the compensator on string 7 and it opened up the usage of the two main chords (or grips) I subconsciously avoided because they didn't sound good (D-major and F# minor). Love. The. Compensator. Rod. The best $25 I ever spent.

Tucker, I like your thinking. It further simplifies what I’m trying to accomplish. Do you add the 7th string compensator to all of your pedals, or just certain ones? I keep consistently hearing about adding it to the A pedal (Emmons copedent), but am hearing mixed findings about adding it to B&C pedals….

And yet another question…..I use a Peterson tuner, I’m imagining that I will have to still use the sweetened tunings on most strings, but will now have to tune the 7th string by ear with the added compensator? Is this correct?

If you use the Peterson sweeteners from Newman, I think you don't need a compensator at all. As in... the note you would want to tune the F# to in the pedals-down world is already the note you're tuned to. Or it will land very close when you step on the pedals and cabinet drop (detuning) naturally flattens the pitch few more cents.

Can you (or somebody) tell me what the offset is for the C# note, and then what it is for the F# note in the Peterson system you're using?

There are different opinions on this. Bear with me here...

If we assume that you tune the F# string to work well in the B-Major chord (i.e., in the no-pedals world, using string 10-8L-7), the main intervals you're needing to fix happen when you move to the pedals-down world:

D-Major (strings 9-7-6B) - The 7th string is the 3rd of this chord, so it needs to be tuned relative to the root note you have on string 9.
Given the way the ear works, you have some latitude as to where to put a note that's serving as the 3rd of the chord (a range that's about 14 cents wide), so this chord won't drive the decision. However, you often add string 5A to this position to get a Major-7 and that gets us into much tighter situation... which is the same situation as the next chord below, where you have 5A beating against string 7:

F#m (strings 7-6B-5A) - The 7th string is the root. But we're in a situation where the 5th of the chord (string 5A) is already tuned-up and set in stone, so you're tuning 7 against that. And you don't have much freedom of choice. The root-fifth relationship only allows a very narrow range, like offsets that are no more than about 5 cents apart. Therefore, this chord position will determine exactly where you need the F# to move to and "land" when you go into the pedals-down world.

Given that string 5A is the finicky-relationship string you're setting up your 7th string compensator to match, it would be logical to connect that pull-rod to slightly flatten the 7th string when you step on the A-pedal.

However, a lot of people (including me) opt to connect it the B-pedal for a couple of reasons. First, almost without fail, when I use the A-pedal against string 7, the B-pedal is going to already be down (for one of the two chord positions listed above). Meanwhile, if you were to put a compensator rod on the A-pedal, you would also have to put another one on the C-pedal, since it also gives the same note on the 5th string. But by putting that pull on the B-pedal, one rod compensates both the AB and BC positions.

And then there's this very minor issue of the string making a slight 'bobble' in pitch up and down as you work the A-pedal. Here, I'm thinking of, say, on the D-major chord since you can hit that 5th string open then step on the pedal to bend into a brilliant Major-7 chord, or work the pedal up and down for licks. This 'bobble' in pitch on the 7th string won't happen if the compensator is attached to the B-pedal, which gets a lot less movement in these positions. But this is a very minor consideration, especially if there is any vibrato in play at that moment.
